I want to test static pressure for Energy Star version 3 in a split heat pump with the air handler in an interior closet so it does not have any return air duct the filter is in the slot at the bottom of the air handler. The inspection form requires 2 inputs a supply side static pressure (I took it in the riser plenum attached to the Air handler.) and a return side static pressure that is supposed to be between the filter (slid in the bottom of the Air handler) and the blower fan. The contractor says he doesn't think he needs to take the return side static pressure because there are not any return air ducts but he will not allow me to drill a hole in the cabinet between the filter slot and the blower. What do you suggest I do to get an accurate number?

Thank you in advance for any help you can offer.
